That’s according to Bicycle Retailer but I’m thinking perhaps the Tour de France is a bit larger. Bicycle Retailer claims Sea Otter hosts around 10,000 competitors and 50,000 fans but I know there are stages of le Tour that see total spectators in excess of 100,000. Anyway, Sea Otter is huge and I’ll certainly agree that it’s the largest cycling event in the US.
Mudhunny and I went out to Sea Otter a few years back and mudhunny even raced the cross-country course. This year’s Sea Otter Classic takes place April 17-20 at Laguna Seca near Monterrey, CA.
